So my original series 1 watch is broken. I dropped it about a week or so back and all appeared fine but then as I pulled it off the charger the next day, I could see that the sensor on the back was loose and only thing keeping it attached to the main body of the watch was some thin wires. The sensor popped back on okay and again appeared fine but then when I tried using the fineness tracking it doesn't track the heart rate and also noticed that it now keeps auto locking and doesn't unlock with the phone. I've looked on the Apple site and they want circa £175 GBP for an out of warranty fix. As far as I'm concerned that's ridiculously over priced, especially as I can get a new original series 1 for £210 GBP from some retailers. I really don't want to spend more than a £100 GBP. Any suggestions on a cheaper fix?
